A new bug has been discovered on the iPhone that can cause WiFi to crash. This doesn't require anything too complicated. Just connect to a specific WiFi network. Once you do, you won't be able to connect to that WiFi network or any other. But I will explain to you for sure what is happening.
CAUTION: Doing so spoils your iPhone's WiFi! do not try
This week an expert reverse engineering user, Carl Schou, encountered a problem while trying to connect to his personal hotspot named %p%s%s%s%s%n. When the tried to make the iPhone WiFi it was disabled. However, whenever I tried to activate it, it turned off. Then he changed the SSID name to see if it solved the iPhone problem and it didn't.
However the site bleeping computer also ran some tests. That said, the same happened and it is no longer possible to access any WiFi network.
A bug like this is something very serious. Especially because some people can take advantage of this to harm people who try to connect. So leave them without WiFi.
What seems to be causing this issue is the iPhone's interpretation of the %.
If this problem happens to you, there is a way to solve it.
For that go to the definitions. Afterwards in the search, at the top, start writing Reset. Press reset network settings. Then again in Reset network settings. This way the problem will be solved. However, don't forget that this will erase any Wi-Fi passwords you have stored on your iPhone.
It's definitely a strange bug but it only really affects those who connect to the WiFi network with strange characters. So be very careful with the wireless networks you connect to. Is that otherwise you may have serious problems on the iPhone, since not being able to connect to networks can even be a drag.
